Update on my 1045T rig.... definitely not a software issue. I tried a fresh install of win7 on 2 different drives and I couldn't keep it running long enough to install

Symptoms:
- starts up (sometimes) and either hangs on boot or boots to windows, runs 10-15 minutes and screen goes blank (790GX IGP and HD6850 same effect) it won't force off or reset* and I need to unplug it to shut it down.
*It's not the power button- disconnected the case buttons and used the ones on the board to check it (same effect)

I would test the PSU but sounds like motherboard issues. HAve you ran a mem test?

I'll replace the PSU 1st and if the problem stays then I'll know the old one is good (save for next rig or spare) but I'm leaning towards mobo as well. Don't really want to try much else until I rule out the psu.

I would run a ram test but unfortunately this is my last DDR2 board and it won't run long enough to test

Speaking of my chip, what do you guys make out of these temps? Loaded after a few mins of WCG and FAH running together. I'm running a Corsair h70 with it, with 2 noctua ~55cm fans. They're set up for exhaust instead of intake like they supposedly recommend. I know the 920 is a hot little bastard, but I expected these temps to be what I would get after some overvolting, not at stock volts (which is 1.2, if it matters any).

I though you did away with all your ddr2 boards for some reason. I guess the memory would be kinda hard to swap out for testing. If you need a stick for testing let me know. A certain somebody sent me some shorty smurf sticks, but they run great.

I have messeged the guy I traded with and hope he can figure out what to do. Hope I don't have to RMA

You probably have but I will ask anyway. Have you tried clearing the bios? I have had strange crap happen when I put the 1055t gigabyte system, the x2 555 and the other 1055 Msi system together the first time and it all cleared up after a cmos clearing. They wouldn't boot, just spins the fans slow upon hitting the power button the first time. After the resetting of the bios they worked just fine.

On another note, my bedroom where 2 of my cruncher live got quiet warm today. We turned the a/c down in there last night and forgot to crank it back up some this morning. I can so though the system pulled through the hot temps and ran fine. I have since cranked the a/c back up. I am also going to probaly bring the x2 back online within the next couple days. All I need to do is clear a space for it next to the other 2 Linux boxes and boot it up. It is already loaded and setup as all I did when I replaced it with the 960t was shut it down and move it out of the way.

I have that issue with a certain cooler. I tried it on 2 diff boards and it rig just won't work. I thiink somehow the mount is touching some of the boards circuitry and causeing it to short and not run. The boards work fine with diff coolers.

I guess now I have a cooler I can't use. May sell it to recoop my lose a lil. dunno yet
